A Wireless Sensor Network (WSN) is a network composed of a large number of nodes that sense, collect, transmit, and deliver data to where it is needed. It involves set of isolated urban areas covered by sensor nodes (SNs) monitoring environmental parameters. Mobile sinks are mounted upon urban vehicles with fixed trajectories (e.g., buses) providing the ideal infrastructure to effectively retrieve sensory data from such isolated WSN fields. Existing approaches with single hop transfer of data from SN that lie within MS range and heavy involvement of network periphery nodes. In Existing Mobicluster Protocol used with Rendezvous sensor nodes for minimizing the overall network overhead and energy expenditure. This protocol use fixed MS track that have no special focus on amount of data that leads to very long delivery delay. Our proposed protocol KNN employs dynamic path selection which is very flexible increases energy reliably and efficiently compared to the previous approach. Hence this protocol aims at achieving overall network overhead reduction, energy consumption and prolonged network lifetime.
